PIN FOR BROOCHES ANI) OTHER ARTICLES.

Application filed February 24, 1914.

To all whom it may concern:

Be it known that I, JAMES A. DonAN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Pins for Brooches and other Articles, of which the following is a full, clear, and exact description.

The heads or eye portions of the pins or tongues for brooches and other articles of that general character, have been formed in a great variety of ways, and with different objects in view.

The present invention has for its ob ect to construct such head or eye portions in a simple manner, and so that there shall be no diminution in strength at this most vulnerable point of the pins or tongues. The invention broadly stated, consists in heading up the end of the wire so asto geta portion thereof standing substantially at right angles to the axis of the pnrand then so modifying this cross-piece that 1t may be turned up toward the main portion of the pin to form the eye and provide a portion which serves as a stop which requires the development of the resiliency of the pin in order to connect it with the pin guard or catch,'as I will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a perspective view illustrating a .first operation followed in one embodiment of the invention. Fig. 2 is a side elevation of the device of this first operation. Fig. 3 is a side elevation similar to Fig. 2, but with the fins trimmed off. Fig. 4 is a side elevation showing the device shorn of part of its cross-piece, and ready-to be bent up into finished form, andFig. 5 is a side elevation showing the formed head or eye. Fig. 6 is a side elevation illustrating the finished pin tongue applied to an ordinary pin joint. Fig. 7 is a cross-section on the line B, Fig. 5. Fig. 8 is a side elevation, Fig. 9 1s a plan view, and Fig. 10 is a side elevation in finished form of a modified form of they pin tongue, wherein the head portion is fiattened. Fig. 11 is a side elevation, Fig; 12 1s a plan view, and Fig. 13 is an elevation n finished form and applied to a joint, showing another modification; and F ig. 14- illustrates the purpose of the back-stop consti- Specification of Letters Patent.

tuting an added feature of the device shown in Figs. ll, 12 and 13.

In the manufacture of pins of the class herein referred to, it has always been a source of expense and trouble to secure enough metal in the head or eye to form a strong and substantial bearing point for maintaining a spring pressure when the pin is engaged in its catch. There are two methods in most common use; one of which is to form a coil in the end of the wire and flatten it, and the other is to cutout a blank from fiat stock and then round and point the stem or piercing portion. In the case of the coiled construction, the coil must be fiattened severely in order to secure a large head, and this results in the weakening of the pin at the juncture of its stem and head and where the greatest strain occurs in use. Where such flattened heads have been provided with a stop, bump, or projection to come into contact with the bottom of the joint in order to make the pin spring, continued use of the pin serves to round off this bump and wear it away until it is no longer eflective. In the case of the pins cut from a blank of flat stock, it is to be said that the process is expensive and practically is avail able only on high-priced goods. Moreover, this construction has the weak point immediately adjacent the juncture of the stem and head where the pin is most vulnerable.

I11 carrying out the invention, I take a piece of round wire, as l, and at some time point it, as at 2, and upset or swage the opposite end, as at 3, so as to practically make a T shaped structure. Then the fins, as I, are removed so as to leave the main portion of the head standing and projecting from opposite sides of the pin as shown in Fig. 3, and then one side of the projecting head is cut off, as at 5, to make it shorter than the other side 6, as shown in Fig. 4, and then the thus prepared pin is'bent over suitable coiling dies, so'as to form aneye or head with a large, flat bearing surface to engage the brooch at the base of the pin joint, as shown in Fig. 6, and which is so far in front of the vertical center line of the eye, that it is impossible for it to have any backward movement on the brooch or base of the pin joint so as to pass under the center'and lose its spring. This shorter side 5 of the head has its end finished off at a slight angle so as to take a square, flat bearing at the base of the pin joint to thereby normally support the pin left between these parts, as indicated in 'Figs.

,5 and 6, so that when the pin stem is forced down, it strikes the head, and the coil acts as a spring; that is to say, there is no 1 6 point of the pin that bends, but the bending is .distributed principally over the coil andonly partly in the pin stem, and hence it practically impossible for the pin to EE-63k- Howfever, as above stated, it is within my invention to have the end of the longer side f the head touch the stem of the pin in its normally finished form. These facts will be more apparent by reference to vFig. -.6, wherein the pin is mounted in an ordinary pin joint 7 If desired, when the pin is formed of round wire, the entire inner circumference of the eye or head may be flattened as at .8, Fig. 7, so as to get a wider bearing on the pivot or rivet which would give a longer life to the pivot or rivet, and avoid the chance of wearing a groove in it, which is liable to happ when the ins d of t e eye is lef with curved surface.

he constr c o sho n in Figs- 8 to 2 illustrates anoth r ay o g tting a s bstant a y c l a d interior v fl en d ey and in this instance the cross-head is formed a plfiviously described, and then flattened as indicated at .9, particularly in Figs. 9 and 12 and then this portion is coiled up as illustrated in Fig. 10. In this construction als a back-stop 1 0 may be orme the nction of the backstop being, as illustrated i Fig, 14, to prevent the pin tongue from turning backward too f;ar.- This back-stop may be swaged or upset on the round wire, or on th flattened structure.

The invention is applicable to pins for use with all styles of joints, including those where a separate pintle, rivet, or pivot is 'used, as well as where such pivot. is integral,

and also where the pivot is suspended in the head of the pin itself. It may also be used in joints of celluloid or other material than metal, as well as in metal joints.

What I claim is 1.. A pin for brooches and other articles, comprising a stem having one of its ends swaged at right angles to the longitudinal axis of the stem to form a cross -piece projecting from opposite sides and bent to form an eye to engage a joint on the brooch or other article, said cross-piece having the end of .one side projection finished to have a flat bearing at the base of the joint in front of the vertical center of the joint, and its other side projection extending toward the pin stem.
